Abstract

A method is described for removing an impurity from a gas. The method comprises the steps of conveying the gas through a solid-state gas purifier comprising an alkali metal ion conducting membrane having a first electrode located on a first surface thereof exposed to the gas, and a second electrode located on a second surface thereof. A current is generated that flows between the electrodes to transport alkali metal ions to the first surface of the membrane to react with an impurity within the gas to form a non-volatile species that is retained on the purifier. The current may be periodically reversed to release the impurity from the purifier in order to re-generate the purifier.
